FIELD: image forming devices.
SUBSTANCE: invention relates to the field of devices for presenting a changing information material and can be used to create devices for demonstrating outdoor video advertising. Invention is directed to solving the problems of creating a new type of LED video screens for the advertising industry, consisting of a set of long (up to 10 meters) LED lamellas. LED lamella is a long strip, the front surface of which is covered with LEDs. Lamellar LED screen consists of several LED segments connected in a single LED surface. Each LED segment includes a segment frame, several LED lamellas and one or more control units. Lamellar LED screen has a simple and convenient system for replacing LED lamellas and control units. Devices for fixing the elements of the LED screen are located on one line on one side of the screen, which greatly simplifies the replacement of the elements of the LED screen. Elements of the screen are fixed on the segment frame using guides and locks. Guides block the movement of the elements of the LED screen along two axes, and on the third axis the locking is effected with the help of magnetic locks. Magnetic lock consists of a permanent magnet and a rod. Permanent magnet holds the lock on the segment frame, and the rod blocks the motion of the LED screen element. LED lamella is manufactured with a slight bend that straightens when mounted on the segment frame, and the resulting elastic force reliably presses the LED lamella along its entire length to the segment frame.
EFFECT: creation of a LED screen with LED lamellas up to 10 meters long; providing a tight pressing of LED lamellas to the segment frame along their entire length.
